Abstract
The invention concerns a conveyor belt scraper (10) which includes blade segments (12) each arranged to scrape a portion of the width of a conveyor belt (22). Each blade segment is supported by a bracket (14) which is mounted to a link (16.1) of a deformable, parallelogram linkage (16). An inflatable hose (30) extends through and acts on the linkages to urge the blade segments against the conveyor belt. The link has a projecting, holed boss (42) and the bracket has a recess (40.3) to receive the boss with the hole of the boss aligned with a hole in the base of the recess to receive a fastener (50) that connects the bracket to the linkage in thermally transmitting relationship. This relationship reduces heat degradation of components of the scraper.
Claims11
A conveyor belt scraper comprising:
- blade segments;
- a bracket supporting each of the blade segments;
- a deformable linkage including a plurality of links, with one of the links, in use, being an upper link;
- means acting on the linkages to bias the blade segments against a conveyor belt;
- and
- an upstanding, holed boss located on the upper link;
- wherein the bracket is connectable to the deformable linkage;
- wherein the bracket includes a recess to receive the boss;
- and
- wherein the bracket includes a hole in the base of the recess such that the hole of the boss aligns with the hole in the base of the recess for reception in the aligned holes of a fastener that serves to connect the bracket to the linkage in thermally transmitting relationship.
A parallelogram linkage for a conveyor belt scraper according to any one of the preceding claims wherein the linkage includes:
- a plurality of links hinged to one another, with one of the links, in use, being an upper link;
- and
- an upstanding, holed boss located on a upper link;
- wherein the boss is receivable in heat transmitting relationship in a recess of a blade segment supporting bracket which in use supports a blade segment that performs a scraping action on a section of the width of a conveyor belt.
